IG6 PROCEEDINGS OF THE ACADEMY OE 



name was proposed for a species of that genus. Its generic characters are the 

 presence of the palatine teeth, the notched dorsal fin and the three super- 

 numerary nearly perfect lines on each side. 



VII. AcANTHOLEBIUS Gill. 



The Chiropsis nebulosus of Girard differs from the true Chiri by the develop- 

 ment of the spinous dorsal, the presence of only three continuous super- 

 numerary lines on each side, and the absence of palatine teeth. It is as nearly 

 allied to Hexagrammus as to Chirm. 



6. AcANTHOLEBIUS NEBULOSUS. 



Syn. Chiropsis nebulosus Girard. 



VIII. Pleurogramiius Gill. 



Among the fishes referred to Chirus or Labrax, there is one distinguished 

 by the presence of teeth on the vomer and palatines, an entire dorsal fin, and 

 the possession of one supernumerary dorsal and two supra-anal lines. For 

 this species, the generic name of Pleurogrammus is offered. 



7. Pleurogrammps monopterygius. 



Sun. Labrax monopterygius Pallas. 



IX. Grammatopleurus Gill. 



The Labrax lagocephalus of Pallas is the type of another unnamed genus 

 of Chiroids. It is distinguished from all others of its subfamily by its cycloid 

 scales. The dorsal is divided, and there are four supernumerary lines on each 

 side. 



8. Grammatopleurus lagocephalus. 



Syn. Labrax lagocephalus Pallas. 



X. Anoplopoma Ayres. 



This genus is a valid and very distinct one, but its describer has mistaken 

 its affinities. It is a Chiroid, but is the type of a distinct subfamily. 



COTTOIDS. 



XI. Megalocottus Gill. 



The Cottus platycephalus of Pallas appears to be most nearly related to the 

 genera Porocottus and Boreocottus Gill, but to be distinguished by the presence 

 of palatine teeth. 



9. Megalocottus platycephalus. 



Syn. Cottus platycephalus Pallas. 



XII. Clinocottus Gill. 



Clinocottus differs generically from the Oligocottus maculosus Girard, by the 

 absence of palatine teeth, the presence of prickles on the body, the entire 

 anal fin and the form of the head. 



10. Clinocottus analis. 



Syn. Oligocottus analis Girard. 



XIII. Blennicottus Gill. 



This genus has been also confounded with Oligocottus by Girard, but 

 decidedly differs in the form of the head, its armature, and the structure of 

 the anal fin.
